Abstract
(EN)
Techniques are disclosed for presenting users with relevant data and statistics related to the operations of an industrial system. Data obtained by a SCADA system may be stored in a real-time status database (which reflects the current process data of the industrial system) and a historian database (which archives the process data from the industrial system as it changes over time). A user may request from the SCADA system process data obtained during a specified period of time. The request may be subdivided into a plurality of time intervals, and process data associated with each time interval may be analyzed to determine one or more salient values that are representative of the interval. The salient values associated with each time interval then may be transmitted to the user in response to the process data request.

L'invention concerne des techniques de présentation, à des utilisateurs, de données et de statistiques pertinentes relatives aux opérations d'un système industriel. Les données obtenues à l'aide d'un système SCADA peuvent être mémorisées dans une base de données d'états en temps réel (qui reflète les données de processus actuelles du système industriel) et dans une base de données d'historiques (qui archive les données de processus provenant du système industriel car elles changent au fil du temps). Un utilisateur peut demander au système SCADA des données de processus obtenues pendant une période de temps spécifiée. La demande peut être subdivisée en une pluralité d'intervalles de temps. Les données de processus associées à chaque intervalle de temps peuvent être analysées de façon à déterminer une ou plusieurs valeurs importantes représentatives de l'intervalle. Les valeurs importantes associées à chaque intervalle de temps peuvent alors être transmises à l'utilisateur en réponse à la demande de données de processus.
